Hello,
Thanks for the upload of these historical resources, they are really interesting. I note that they are no longer in copyright under crown copyright, however, as the digitiser of this work I am writing to you to ask if you would let us re-use the scans of the maps as part of our gereferenced SABRE Maps historical coverage project.
https://www.sabre-roads.org.uk/maps/
We are a not for profit society that is free to join aimed at the study of roads and maps of the UK and Ireland.
We would be able to overlay these historical maps onto modern maps, so that it would be possible to see the historical data in relation to current features.
You can see this functionality in action if you choose one of the One Inch layers from the 1950s-70s.
We also have an extensive wiki aimed at the collection of historical information surrounding the road network and its history.
Archive.org suggest that the way to request re-use is to leave a review, so apologies for not being able to contact you directly.
Regards,
Chris
